Title: Measuring method for plated film thickness of semiconductor device
Inventor: KOBAYASHI TAKAAKI
IPC: H01L21/66
Filed: 1985-10-07
Abstract: PURPOSE:To observe film thickness visually and easily by forming a monitor pattern for measurement, which takes a trapezoid protruded from a semiconductor substrate and has uniform height, around a central section pattern and shaping a transparent photo-mask onto the monitor pattern. CONSTITUTION:A monitor pattern 3 is formed by shaping sub-patterns 3b, in which two quadrilaterals are connected, at each corner of a central section pattern 3a. A transparent photo-resist is applied onto the whole surface except the central section pattern, and a first photo-resist pattern 4 is formed. A substrate 1 is dipped into a gold plating solution, and gold wirings 5 are shaped through gold plating. When a metallic film 6 in gold plated onto the central section pattern 3a exceeds the film thickness of the photo-resist pattern 4 in a growth process, it extends in the lateral direction and covers the upper sections of the sub-patterns 3b because it grows in an isotropic manner in three-dimensions. The size in the lateral direction of the cover is observed from an upper surface and can be determined because the photo-resist is transparent. It can be assumed that the sum of the size in the lateral direction and the film thickness of the photo-resist is equivalent to the thickness of the metallic film 6.

Title: Controller
Inventor: YAMAMOTO TSURASHI
IPC: G01C19/56
Filed: 1984-10-25
Abstract: PURPOSE:To oscillate a dynamical oscillation system like an oscillation gyroscope at its natural oscillation frequency and to hold its amplitude constant by decreasing the output signal of a controller according to an increase in the signal of a deviation detector and supplying it to a driving device. CONSTITUTION:The output voltage VP of a displacement detector 11B is applied to the driving device for the oscillation gyroscope 10 through a blind sector element 12, a control circuit 14, etc., to constitute a control closed circuit. Then, the voltage VP is passed through a setting element 15 having a gain contact P to obtain a voltage PVP, and a DC voltage 2VD is supplied as a blind sector voltage to the element 12 through a full-wave rectifying element 16 to obtain a blink sector of + or -VD. When the input voltage VP of the element 12 increases, the blind sector voltage VD also increases and the ratio of the output of the element 12 and the input VP, i.e. equivalent gain of the element 12 becomes small according to an increase in input VP because of the influence of the voltage VD. Therefore, the one-round closed loop has an automatic control function which makes the signal amplitude constant and also has a function which holds the resonance frequency of the dynamical oscillation system constant. Therefore, the dynamical oscillation systems is oscillated continuously at its natural oscillation frequency to a constant amplitude without reference to temperature variation.

Abstract: PURPOSE:To rapidly execute an image recording operation by holding an image recording carrier by a driving drum and a nipping roller, sub-scanning and carrying to a pair of carrier rollers, projecting a recording beam mainly scanned in a direction substantially orthogonal with the sub-scanning direction and recording an image.

Title: Method for controlling semiconductor laser sensor
Inventor: TORII NOBUTOSHI
IPC: H01S5/00
Filed: 1991-08-12
Abstract: PURPOSE:To enable the output value of a semiconductor laser sensor to be set optimum and be kept optimum. CONSTITUTION:The peak value of the received quantity of a light, which is sensed by a CCD light receiving element 2, is measured (3, 4). In a semiconductor memory 5, stored are the peak value and the output of a second stage buffer 7, which stores a laser command value when the light receiving element receives the light (the measurement of the peak value of the light receiving element is delayed by two periods from the time when the laser outputs the light). In each address of the semiconductor memory 5, stored is such a laser command value that the measured peak value is made to coincide with a set value. The command value for the laser is changed by modifying it in succession, and a feedback control is so performed that the measured peak value is made to coincide with the set value (8, 9, 10). When teaching the robot using a laser sensor and when playback-operating it, the set value is changed by changeover commands, and the laser outputs suitable to the respective cases are made obtainable. Even when outputting the laser beam of a visible light, there is no possibility of damaging the eyes of an operator when teaching the robot. Also, the CCD light receiving element is prevented from being saturated too.
